@tigerpro Thank You VERY MUCH!
This can help me choose the smartphone model I need.:beaming_face_with_smiling_eyes:

@moem Thanks for your reply.
But what's the use of video recording with my OPO's camera if I can't even check if it's a good take?
P.S.: anyway if you can help me, I'll be grateful.

Hello!
I've not been to this forum for a long time.
I already had some experience with ubuntu on my Oneplus One and also on Oneplus 3.
Then there were some video playback issues (though not only that).
I am talking about the MP4 format.
On Oneplus 3 video was not played at all.
And only short video (approximately 5-10 minutes) was played on Oneplus One.
So questions to Ubuntu Touch users of all smartphone models:
Does your smartphone model play 50+ min or 500+ MB video?
Please give me an answer in the format like:
My model is ... - the problem with the video is the same as yours
or
My model is ... - I have no problems with the video.
Thank You All in advance.
Kyrylo.

@commisde Hey!
If I'm not mistaken there is no problem with USB-tethering on Nexus 4.
You should just type those two commands in terminal:

$ android-gadget-service enable rndis
$ sudo tethering enable

@Lakotaubp
Yep!
I can mistaken, maybe order should be different.
I've just messed up with those commands and suddenly it worked.

@slowcyclist Thank You very much!

I've just copied and pasted some of lines from your topic and USB-tethering WORKS NOW!!!
(I don't know why:beaming_face_with_smiling_eyes: )
Here are that commands:
$ sudo android-gadget-service enable rndis
$ sudo bash /android/system/halium/usr/share/usbinit/setupusb reset
$ sudo bash /android/system/halium/usr/share/usbinit/setupusb rndis
$ sudo ifconfig rndis0 up
$ sudo tethering enable

Please, test it sombody else with Oneplus3.

Thank You all!
I was confused by the fact that someone said that he had this feature on Oneplus 3.
So...
I hope we will have this in nearest future.
Have a nice day!

@gischpelino Your idea sounds good.
Thank you for clarifying the question.

@Lakotaubp No results with UT Tweak Tool.
Is it common issue?
Has anybody USB-tethering working on OP3?

Hello!
I have a issue with usb-tethering.
When I type in terminal
$ android-gadget-service enable rndis
rndis enabled
$ sudo tethering enable
Device "rndis0" does not exist.
Error: Connection 'tetherning' does not exist.

I have had this problem for a long time. I installed the new version several times, but to no avail.
This feature worked fine on Android, but does not work on UBports.

Does anyone have any idea where to look for the cause of the fault?
Thanks in advance.

@peat_psuwit Hi!
About video recording on OnePlus 3.
When I press the record button everything freezes, and there are no errors in the terminal.
Last line in the terminal:
[PERFORMNCE]: Last frame took 60 ms to render
Here are a couple of screenshots:

I hope this will be usefull... somehow
P.S.: Great work. Thanks a lot.
P.P.S.: Does IOS werx... somehow?

@peat_psuwit Thanks! I've reinstalled UT and camera works now.
But video recording still doesn't work.
Where where should I provide debug information if you need it?

@Capsia Yep, I know.
But on Android you can choose "LTE only", "WCDMA only", "LTE and WCDMA", etc., when you enter Engeneering Mode. (usually you can access by dialing *#*#4636#*#*)

Hello!
On Android it is possible to choose the type of mobile network, when you enter Engeneering Mode. (usually you can access by dialing *#*#4636#*#*)
I mean "LTE only", "WCDMA only", "LTE and WCDMA", and etc.
Is there way to do something similiar on UT?
Is it possible at all,
can such a feature appear in the future?
Thank you in advance for clarifying the question.

Hi!
I am new to UT on Oneplus 3.
I had working camera (photo only).
Then I've installed gst-droid following all instructions.
And camera-app stops working.

$ cd /opt/click.ubuntu.com/com.ubuntu.camera/current/3.1.2+gstdroid3
$ GST_DEBUG=droidcamsrc:4 ./camera-app --desktop_file_hint=~/.local/share/applications/com.ubuntu.camera_camera_3.1.2+gstdroid3.desktop

Hi!
I have a question about USB tethering on Oneplus 3.
Internet connection works well.

In terminal I've entered commands:
$ android-gadget-service enable rndis
rndis enabled
$ sudo tethering enable
Device "rndis0" does not exist.
Error: Connection 'tethering does not exists.

Does it work at all?
Or it's a bug.
Where I should report a bug?(additional question)
Thanks in advance.

Try to unset and set developer mode
Be sure you enabled USB-debugging in developer option
then connect your phone with USB cable it should ask you for permissions.
If it ask confirm and on PC in terminal type "adb devices".

Hi!
First of all!
Have You bootloader unlocked on your phone?

Hello everyone!
Problem is solved.
Ubports-installer downloads files to ~/.caches/ubports/ (on Ubuntu Linux)
So I've downloaded https://cdimage.ubports.com/devices/halium-unlocked-recovery_oneplus3.img and
only large files from https://system-image.ubports.com/16.04/arm64/edge/oneplus3/index.json from the very ending of json file, but very last type:full version (not type:delta).
Then I've put them to ~/.cache/ubports/oneplus3/firmware/ and ~/.cache/ubports/pool/ respectively.
And the remaining few bytes Ubports-installer downloaded yourself.
So.
Maybe this information will be useful for someone else
Thank You all!
